Definitions

the subject invention relates to a screw for fastening at least one first component to a second component, which is made of wood or the like.
is made consisting of a metal, in particular of rolled steel, produced bolts, which is formed at one of its two ends with a screw head and at its other end with a screw tip and which at least over which abuts the screw tip part of its length with a Screw thread is provided, wherein the screw tip is formed with a recess which extends into the adjacent to the conical screw tip portion of the screw bolt and which is bounded by an axis at least approximately parallel to the axis of the screw bolt.
Known screws are formed at their one end with a screw head and at the other end with a tapered screw tip, wherein the tapered screw tip and the bolt are formed with a thread.
the mode of operation of such a screw is to fit into the second component of relatively soft material, e.g. Wood, is turned, which can be provided with a bore, wherein it is screwed by its rotation in the material.
the material of the second component which is located in the course of the screwing, must be displaced. The greater the specific hardness of this material, the greater the resistance that occurs when turning the screw. In addition, this can blow up the second component.
a screw which is formed on its conical screw tip with a recess which is bounded on the one hand by a plane parallel to the screw axis and the other by a plane lying in a normal plane on the screw axis surface, wherein the surface located in a normal plane in that area the conical screw tip is in which this merges into the cylindrical bolt.
the entire screw tip is approximately half-cone-shaped.
a screw which is also formed with a semi-conical screw tip, wherein a transverse to the screw axis boundary surface to the normal plane on the screw axis has an angle of about 45 °.
this boundary surface still ends in the region of the conical screw tip or outside of the cylindrical screw bolt, which is why the technical requirements are not met by this known screw because the accumulating in the recess material can not get out of this.
the subject invention is therefore the object of the invention to provide a screw through which the technical requirements are optimally met. This is inventively achieved in that further the recess is bounded by a flat or curved surface enclosing an acute angle with a normal plane to the axis of the bolt.
the plane enclosing an acute angle with a normal plane on the axis of the bolt may be inclined against the direction of the screw thread.
the plane or curved surface with a normal plane on the axis of the bolt an angle between 5 ° and 45 °.
the screw 1 shown in Figures 1 and 1a has a bolt 10 with a screw head 11, an adjoining, without screw thread formed pin member 12, an adjoining formed with a friction surface 13 bolt part, an adjoining formed with a screw thread 15 bolt part 14th and with a conically tapered screw tip 16.
the screw tip 16 is formed with a flat surface 17 which extends approximately in the axis of the screw 1, which extends beyond the end of the conical screw tip 16, that is, beyond the beginning of the cylindrical pin member 14, and which through a to a normal plane on the axis of the bolt 10 inclined surface 18 is limited. By the side edges of the surface 17 cutting edges are formed.
the conical envelope having a screw tip 16 is formed with up to 180 ° extending, semi-conical recess in which 1 can accumulate material during rotation of the screw.
the material does not have to be displaced by the screw tip 16, the resistance decreases when screwing in the screw 1 or the risk that blasting of that component, in which the screw is screwed, is caused, reduced.
the surface 18 with a normal plane to the axis of the bolt 10 includes an acute angle between 5 ° and 45 °, when screwing the screw 1 into a component that in the recess formed by the surfaces 17 and 18 accumulating material from this Out recess, whereby a jam, through which the component could also be blown is avoided.
the surface 18 may be flat or curved. In addition, it can run in different inclinations to the normal plane on the screw axis. Furthermore, it can run in the direction of the screw thread 15 or against this direction.
